This paper documents an unusual and possibly significant phenomenon: The export of skills embodied in goods, services, or capital from poorer to richer countries. We first present a set of stylized facts. Using a measure that combines the sophistication of a country's exports with the average...

The current perspective on the flow of people is almost exclusively focused on permanent migration from poorer to richer countries and on immigration policies in industrial countries. But international mobility of people should no longer be seen as a one-time event or one-way flow from South to...

International negotiations on climate change have been dogged by mutual recriminations between rich and poor countries, constricted by the zero-sum arithmetic of a shrinking global carbon budget, and overtaken by shifts in economic power between industrialized and developing countries. To...

This paper estimates how changes in China's exchange rates would affect exports from competitor countries in third-country markets -- in other words, the "spillover effect." The authors use recent theory to develop an identification strategy, with a key role for the competition between China and...

Should the China-U.S. trade agreement prompt relief because it averts a damaging trade war or concern because selective preferential access for the United States to China's markets breaks multilateral rules against discrimination? The answer depends on how China implements the agreement....

The labor force of each industrial country is being shaped by three forces: ageing, education and migration. Drawing on a new database for the OECD countries and a standard analytical framework, this paper focuses on the relative and aggregate effects of these three forces on wages across...
